Wikipedia writes that “Rest In Peace” (from latin: requiescat in pace) is a prayer that the departed may be at peace, not in torment, while awaiting Judgment Day. That seems appropriate for Microsoft.
Paul Graham writes,
A few days ago I suddenly realized Microsoft was dead. […]
I’m glad Microsoft is dead. They were like Nero or Commodus—evil in the way only inherited power can make you. Because remember, the Microsoft monopoly didn’t begin with Microsoft. They got it from IBM. The software business was overhung by a monopoly from about the mid-1950s to about 2005. For practically its whole existence, that is. One of the reasons “Web 2.0” has such an air of euphoria about it is the feeling, conscious or not, that this era of monopoly may finally be over.
